Map of Weather Stations from the Global Historical Climatology Network - The blue pin indicates the location of the current station being plotted below. The darkness of the point indicates the length of the record for each station. The map is dynamic, pan, zoom and click on points to get the station ID number.

Monthly Temperture and Precipition - This is the classic “Climograph” where average monthly temperature (left Y axis) and precipitation (right Y axis) are displayed together. This plot averages data over a 30 year period starting in 1981 and ending in 2010 (commonly referred to as the Normal by climate scientists).

Data Completeness Matrix - This tile plot show the data density for the full length of the record for the current weather station. Every day for the record is represented, where color ranges from blue to red it is showing the daily mean temperature, where gray or white are present means that no temperature data was recorded.

Blue to Red colors reflect recorded daily mean temperature, gray and white represent missing data.

Daily Temperature Range - This plot compares the daily temperature range for a single year (the colorful vertical lines) to the average daily high and low temperature (light gray) and the record high and low temperature observed at the current station (darker gray). Red and blue diamonds indicate when the high or low temperature record was set during the particular year being observed.

This shows daily temperature ranges over the course of a year vs. the average high and low (light gray) and the record high and low temperature ever recorded at this station (dark gray).

Hotness Index - Are the hot days getting hotter and more plentiful? For the Hotness index, a value of 75 for a particular year means that the maximum daily temperature equalled or exceeded 75 degrees Fahrenheit 75 times during the year. If the Hotness index is increasing, both the number of hot days and the temperature on those days is increasing.

The points show the annual variation in the Hotness Index, the red line smooths the data using a loess filter and the gray shading is the 95% CI.

Coldness Index - Are the cold days getting colder and greater in number? The Coldness index is similar; here a value of 25 means that the minimum daily temperature equalled or exceeded 25 degrees Fahrenheit below the freezing point of water (at 32 deg F) 25 times during the year. If the Coldness index is dropping year to year, it means that cold days are warmer and less frequent.

The Coldness Index is defined as the number of days C at which the Fahrenheit temperature relative to the freezing point of water (32 degF) is −C or less. The points show the annual variation, the blue line smooths the data using a loess filter and the gray shading is the 95% CI.

Monthly Mean Temperature Anomaly - This plot illustrates how the monthly mean temperature from the last 10 years compares to the monthly mean temperature calculated using the full record from the weather station. The “anomaly” is calculated as the difference between the last 10 years and the full record for each month.
